Detailed Standards Coverage

prEN 40000-1-3 – Cybersecurity Requirements for Vulnerability Handling

Full Standard Title: Cybersecurity requirements for products with digital elements - Part 1-3: Vulnerability Handling

The prEN 40000-1-3 standard was published in December 2025 by CEN and is poised to become a cornerstone for cybersecurity in Europe. This standard sets out specifications for manufacturers of products with digital elements—encompassing everything from IoT devices to enterprise software—on how to establish, document, and execute robust vulnerability handling processes.

What This Standard Covers & Its Scope

• Holistic Process Guidance: The standard structures vulnerability handling into distinct phases: preparation, receipt, verification, remediation, release, and post-release monitoring.
• Comprehensive Product Inclusion: Applicable to all products containing digital elements (hardware and software), regardless of industry application.
• Alignment with EU Cyber Resilience Act: Designed to comply with Regulation (EU) 2024/2847, covering essential cybersecurity obligations specified in the Cyber Resilience Act.

Key Requirements and Specifications

• Identification & Documentation: Manufacturers must maintain a Software Bill of Materials (SBOM), documenting all top-level software components in a recognized, machine-readable format (examples: SPDX, CycloneDX).
• Vulnerability Management: Processes should identify, assess, and remediate vulnerabilities without delay, with security updates issued separately (where feasible) from functionality updates.
• Regular Testing: Mandates ongoing security testing and review for all digital elements in products.
• Transparent Disclosure: After a security update, manufacturers are required to publicly disclose comprehensive information about fixed vulnerabilities, including severity and remediation guidance.
• Policy Frameworks: Internal policies on vulnerability handling and coordinated vulnerability disclosure (CVD) are mandated, supporting both staff and external reporters.
• Secure Communication: Manufacturers must provide secure, accessible mechanisms for stakeholders to report vulnerabilities, including offering anonymous channels.
• Distribution Mechanisms: Security updates must be distributed securely and, where possible, automatically and free of charge. Advisory messages should accompany updates, informing users about risks and mitigations.
• Risk-Based Enhancements: Where higher product risk is identified, enhanced requirements are activated—such as greater SBOM transparency and machine-readable advisories.

Who Needs to Comply

This standard targets:

• All manufacturers of products with digital elements, including OEMs, software vendors, hardware manufacturers, and integrators.
• Organizations building, distributing, or selling connected devices or software solutions within EU and global markets.
• Any party subject to the EU Cyber Resilience Act.

Practical Implications for Implementation

• Organizational Structure: Teams must be assigned clear responsibilities for vulnerability response and disclosure coordination.
• Process Integration: SBOM generation, vulnerability triage, and security testing should be embedded into existing product lifecycle management processes.
• Customer Communications: Pre-defined channels must be established for advising users on vulnerabilities and available fixes.
• Supplier Engagement: Collaboration with component suppliers and open-source maintainers is necessary for accurate and timely SBOM maintenance.

Notable Changes from Previous Guidance

• Elevates recommendations in ISO/IEC 30111 & 29147 to enforceable requirements—especially regarding CVD and ongoing monitoring.
• Explicit linkage to regulatory compliance with the Cyber Resilience Act, making adherence non-optional for market access.
• Greater emphasis on transparency, automation, and user empowerment.

Key highlights:

• Mandatory SBOM creation in machine-readable formats
• Requirement for secure, rapid distribution of security updates
• Strong focus on coordinated vulnerability disclosure and stakeholder communication

Industry Impact & Compliance

The integration of prEN 40000-1-3 into Information Technology product development is set to transform how organizations monitor, respond to, and mitigate cybersecurity threats. Here’s what professionals need to consider:

• Legal Compliance: For businesses selling into the EU, compliance with this standard is critical due to its alignment with the Cyber Resilience Act. Failure to adopt such practices could result in legal penalties or loss of market access.
• Enhanced Product Trust: By embedding proactive vulnerability management into products, organizations can build stronger trust with customers and regulators.
• Operational Readiness: Organizations must establish or bolster vulnerability response teams, update policies, and invest in automation for SBOM generation and updates.
• Supplier Assurance: The standard compels manufacturers to ensure their entire supply chain is also following best practices, affecting procurement and vendor risk management.
• Timeline: Because the standard aligns with EU regulatory deadlines, organizations should accelerate compliance projects—early adopters will minimize business disruption and demonstrate leadership in cybersecurity.

Benefits of adopting this standard:

• Improved incident response times
• Reduced risk exposure and cost of breaches
• Streamlined certification and audit readiness
• Enhanced brand reputation and customer confidence

Risks of non-compliance:

• Regulatory fines and enforcement actions
• Loss of market access in regulated regions
• Increased vulnerability to cyber attacks and data breaches
• Damage to brand credibility and loss of customer trust

Technical Insights

Common Technical Requirements in prEN 40000-1-3

• Machine-Readable SBOM: Adopt structured formats such as SPDX or CycloneDX for clear, automated dependency mapping and vulnerability detection.
• Coordinated Vulnerability Disclosure (CVD): Implement clear, accessible, and secure channels for external parties to report vulnerabilities; ensure both manual and automated intake.
• Continuous Security Testing: Integrate regular automated and manual testing (such as static and dynamic analysis) into maintenance schedules.
• Risk-Based Rigor: Products assessed as high-impact require enhanced documentation, monitoring, and notification procedures.
• Transparent Release Management: Every security update must be accompanied by user-friendly release notes and advisory messages.

Implementation Best Practices

1. Establish Cross-Functional Teams: Combine expertise from engineering, legal, compliance, and customer support to oversee vulnerability management.
2. Automate Where Possible: Leverage tools that automate SBOM creation, monitor component risks, and verify update delivery.
3. Documentation & Audit Trails: Keep detailed records of vulnerability reports, decision-making, communication, and remediation actions for regulatory and customer assurance.
4. Supplier Collaboration: Regularly update SBOMs in collaboration with upstream and downstream partners; require suppliers and integrators to follow equivalent standards.
5. User Empowerment: Make security advisories and update instructions easy to access and understand; provide guidance for both technical and non-technical users.

Testing and Certification Considerations

• Independent Security Assessments: Engage with accredited testing organizations to verify the effectiveness and sufficiency of your vulnerability management processes.
• Certification Readiness: Documentation and practices set by prEN 40000-1-3 can be leveraged to achieve certifications under EU and global cybersecurity regulations.
• Ongoing Monitoring: Schedule periodic reviews of processes, policy updates, and staff training to maintain compliance as threats and technology evolve.
